Each year, hundreds of Pakistani women are killed by relatives angered by behavior that they think has tarnished the family's reputation, human-rights activists say. At a press conference, it was reported he had killed Ms Baloch "for honour".
According to the report, the police described the incident as "honour killing", adding that her brother had protested at the "kind of pictures she had been posting online" prior to her death. "It seems to be a case of honour killing but we are investigating it", district police chief Azhar Akram said. Baloch was outspoken about her social-media presence and identity. She received multiple death threats and suffered frequent misogynist abuse but continued posting provocative pictures and videos.
Qandeel was reported to have been strangled in her sleep at her family home.
Most recently, Baloch became embroiled in public scandal when she posted selfies with Mufti Adbul Qavi, a prominent cleric, in a Karachi hotel room during the holy Islamic month of Ramadan.
She had said her life was in danger and that she was being threatened via calls on her mobile number and that she did not have security measures installed in her home, the paper said.
Police have said that they are now looking for Waseem, who is now missing.
Baloch's raunchy social media photos challenged social norms in Pakistan, a deeply conservative country where women are often repressed by their family or the community. "It's time to bring a change because the world is changing. let's open our minds and live in present".
"While her approach to fame is not original, the woman herself is an interesting example of how a typically conservative society like Pakistan both vilifies sex and is obsessed with it...."
In a high-profile stunt, she promised to strip should Pakistan beat India in a recent cricket match -- but as the BBC points out, Pakistan lost so we don't know what would have happened.
"As women we must stand up for ourselves". She sought out help from the government, and had hoped for protection.
Qandeel was a media sensation, bold in her videos and considered quite controversial in the country.
Obaid-Chinoy's film was hailed by Pakistan's Prime Minister Nawaz Sharif, who in February vowed to push through anti-honor killing legislation.
